PAPER TUBE FOR TOILET USE.

Application filed March 14, 1914.

T0 all whom it may concern:

Be it known that l, WILLIAM CONRY, a citizen of the United States, residing at Elkhart, in the county of Elkhart and State of Indiana, have invented new and useful Improvements in Paper Tubes for Toilet Use, of which the following is a specifica tion.

The invention relates to improvements in paper tubes used especially for the roll, or core, upon which ctoilet paper is wound, or rolled.

VThe object of the invention is to provide a disintegrable paper tube to be used as a. core, or roll, upon which toilet paper is wound, and which will disintegrate into its component parts when the tube, devoid of the toilet paper, is thrown into a closet bowl,

and readily pass through the bowl and waste pipe into the sewer without obstructing the plumbing. This object is attained by the construction and' assembly of the pieces and parts shown on the accompanying drawing, in whichl Figure 1 is a sectional side elevation of the complete tube; Fig. 2 is a cross-sectional view of F ig. 1 taken at any point through the tube; Fig. 3 is a sectional side elevation of a wrapper partially inclosing one of the cylindrical inner sections; Fig. 4 is a crosssectional view of a cylindrical inner section of convoluted construction.

Similar letters refer to similar parts throughout the several views.

The invention is practically embodied in the accompanying drawings forming a part of this specification, and is formed essentially of the outer wrapper, or binder, A and a cylindrical or tubular core composed of two or more short tubular sections B made of pasteboard or other suitable material. The wrapper, or binder, A is preferablv formed of a soluble, or very absorbent, paper adhesively fastened to and wound i around a plurality of the tubular core sections B placed end to end, and may be convoluted two or more times thereon to produce the necessary rigidity. When cast into water, a toilet bowl, for instance, the tube soon disintegrates, or becomes very pliable, for the moisture pulps the absorbent wrapper A leaving the core sections separate and unbound members which will readily pass into the waste pipe.

Un the drawings, A is the soluble wrap- Specication of Letters Patent.

per, or binder, formed of very absorbent paper, wound around the cylindrically formed core sections B, placed end to end, in contact at E. The core sections B may be made of a single thickness of material and formed with a butt joint D, as in Figs. 1 and 2, but the invention contemplates the use of acylindrical core section, or sections, formed in any manner, of convoluted construction as shown in Fig. 4, or otherwise.

The wrapper A is wound around the core section B in circular convolutions preferably, but may be wound otherwise and the same results obtained. Any suitable adhesive material may be used to fasten the end of the wrapper A to the core sections B, and to itself thereafter to form a consistent body of the component parts of the tube. While the absorbent quality of the wrapper A is absolutely essential to cause disintegration of the tube when immersed in water for some time and under the conditions mentioned particularly, the core sections B must be made of stiff material, preferably pasteboard, to make a rigid tube in its finished construction.

Having thus described my invention, l claim as new and desire to secure by Letters Patent- 1. A paper tube adapted for use as a core, or roll, for toilet paper rolls comprising a core section formed of a plurality of cylindrical members, and means for binding the cylindrical members together, said means comprising a wrapper of absorbent paper which is adapted to be pulped when immersed in liquid, substantially as described.

2. A tubular core for toilet paper rolls comprising a core section formed of a'plurality of cylindrical sections formed of stif'r` paper material, and means for binding the .cylindrical sections together, said means comprising a paper wrapper of absorbent quality convoluting said sections with one or more layers and adapted to be pulped when liquid is absorbed thereby, substantially as described.

3. A disintegrable tube for paper rolls comprising a core section formed of a plurality of cylindrical paper members, and means for binding said paper members together, said means comprising a wrapperfof absorbent material convoluting the cylindrical members withy one or more layers,

substantially as described.
